Issue Nginx make websites hang

[ValentinoG]

Hi

I've been experiencing an annoying problem on an Ubuntu 16.04.6 LTS server, Plesk version 17.8.11.

A couple of weeks ago all websites were hanging. I tried everything, nothing seemed to solve the problem. Then I disabled Nginx and all the websites started to work again.

Since then I tried to re-enable Nginx but with no luck: as soon as I re-enable it all the websites stop working. Nginx is compiled stock, as follows:

nginx version: nginx/1.14.2
built with OpenSSL 1.0.2g  1 Mar 2016
TLS SNI support enabled
configure arguments: --prefix=/usr/share --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --modules-path=/usr/share/nginx/modules --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --lock-path=/var/lock/nginx.lock --pid-path=/var/run/nginx.pid --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --user=nginx --group=nginx --with-ipv6 --with-file-aio --with-http_v2_module --with-compat --with-http_ssl_module --with-http_realip_module --with-http_sub_module --with-http_dav_module --with-http_gzip_static_module --with-http_stub_status_module --add-dynamic-module=/usr/share/passenger/ngx_http_passenger_module --add-dynamic-module=../incubator-pagespeed-ngx-1.13.35.2-stable

Any advice?

Thanks in advance

Do you see entries in /var/log/nginx/error.log and /var/log/messages? Normally when you try to start the service and the service does not want to start, errors are logged there in detail that explain what the trouble is.

Forgot to mention, there are no errors in the log files related to Nginx. And that what's puzzling me.
